DEVICE FOP.. @PEN ING Specification of Letters Patent No.

To all whom 'it may concern.'

Be it known that I, JOHN H. NEviN, of Ogdensburg, in the county of St.Lawrence and State of New York, have invented certain new and usefulImprovements in Gates; and I do hereby declare that the following is afull, clear, and exact description of the same, reference being had tothe accompanying drawings, forming a part of this specification, inwhich- Figure 1 represents a face View of my gate when the same isclosed in black outlines, and an end view of ditto when open in redoutlines. Fig. 2 is a transverse vertical section of the same, the linem, Fig. l indicating the plane of section.

Similar letters of reference in both figures indicate correspondingparts.

rlhis invention consists in arranging a gate or door with a doublesgring hook in combination with a double hand lever and with two postswhereby the door fastens itself when it is shut, well as when it isopened.

To enable those skilled in the art to make and use my invention, I willproceed to describe it.

rThe object of this invention is to fasten a gate or door as well whenthe same is shut as when it is opened, so that the same when it isexposed to the action of the wind is not thrown about and injured. Toaccomplish this object, I have secured to the upright bar A of the gateor to its outer edge a hook B with two noses a ca and connected by a rodZ) to a double armed hand lever C, one end of which extends to theinside and the other to the outside of the gate. The hook B turns freelyon a pivot o and it is subjected to the action of a spring' d which issecured to the upright bar A as clearly shown in Fig. 2. The nose a. ofthe hook B extends to the outside of the gate, and if the gate is shutit catches over a post D the upper surface of which is a little inclinedin order to allow the nose to slide up it, and to catch more readilyover its outer edge. Said post isfurnished with a shoulder e whichprevents the gate passing beyond the required point.

When the gate is opened, the nose a catches under a lip f formed bynailing and AND CLOSING GATES.

screwing a metal plate g over a mortise 7L in a post E, and this post isso placed that it allows the gate to open to the desired point, but nofurther. lVhen my fastening is used for a door, mortises in the sill andin the wall may take the places for the posts D and E.

rlhe spring hook B is operated by means of the double armed hand lever Cand both the noses a a are released by lifting up the end z' of saidlever, and by depressing its other end z". A staple y' is placed overthe spring hook B in order to keep it always in the proper position toact.

It will be noticed, that this arrangement is equally applicable togates, barn doors, or in fact to all doors which are exposed to theinfluence of the wind or which require to be fastened both ways. lf sucha gate or door is left open and without my fastening the wind will slam4it to and fro to the great injury of the hinges and other parts of thedoor or gate and to the great annoyance of the inmates of the house, orof neighboring houses if such slamming of the door or gate takes placeat night. 'Vith my fastening on the other hand the door will be slammedonce only, either one way or the other, and it will then be fastened sothat the wind has no further influence on the same.

By connecting the hand lever C with the double spring hook B, theoperation of my fastening is made quite convenient, and it will be foundof great advantage, also; to doors on steamboats and particularly whenthe same are provided with one or more panes of glass which are veryliable to get broke if the door is left to the influence of the wind.

lVhat l claim as new and desire to secure by Letters Patent, is

Arranging a gate or door with a double spring hook B in combination witha double hand lever C and with posts D and E, to operate substantiallyin the manner and for the purpose set forth.

JOHN H. NEVIN.
